ABSTRACT:
A vehicle plow suspension system designed for use with a large object such as a plow blade is disclosed. The suspension system is disposed between and connected to the plow blade and its associated positioning means, and comprises an expansion spring coaxially mounted about a two-way shock absorber in a sealed housing. The suspension system operates to attenuate both the relative movement between the plow blade and its associated vehicle, and the resultant forces thereby transmitted from the plow blade to the vehicle.
